The AutoFlagger is a traffic control device mounted on a trailer that includes the sign faces of a stop/slow paddle and supplemental signs and lights. The supplemental signs mounted below the stop/slow sign are: WAIT ON STOP and GO ON SLOW. The AutoFlagger is classified as an Automated Flagger Assistance Devices (AFADs) that assist a flagger operation for short-term lane closures, on two-lane highways. A flagger(s) can operate an AFAD by using a radio control unit or by using a cable directly attached to the AFAD. 2 In either case, the flagger can be positioned well away from the roadway and moving traffic. The primary benefit is to enhance the safety of flaggers, while also maintaining positive control of traffic approaching the TTC zone. The purpose of this study is to evaluate prospects for using the AutoFlagger in Virginia. This effort is part of the Maintenance Operations Research (MOR) Program.
